11 Claims. (01. 160-102) This invention relates to windows and to protective material therefor.

One object of the invention is to provide pro tective material for glass windows whereby to eliminate or greatlydiminish the danger to the occupants of a room or loft of a factory or other i building from the destructive damage of air raids More specifically, it is an object of the present invention to provide glass windows with protective material which prevents or lessens to a considerable extent the danger of flying glass and other fragments which would otherwise occur and cause considerable damage and injuryin the interior of the building and to persons inside the building in the event of an air raid.

A further object of" the invention is to provide a protective material having'the above described characteristics and also being highly useful for blackout purposes.

A-further object of the invention is to provide glass windows with protective material secured thereto whereby to eliminate or decrease the likelihood of personal injury and property damage which might otherwise result from an air raid. I

Another object of the invention is to attach the protective material'to the window in such manner that the window may be openedwhen desired wihout detaching the protective material therefrom. This also provides means to allow the decrease in pressure which'builds up'in'side a building due to the initial inrush of air when an explosion occurs.

A further object of theinvention is the provision of means to prevent glass or panes from falling outwardly when the second reaction of the explosion takes place.

Theabove and other objects, features and advantages of the invention will be clearly understood from the following description, reference being had to the accompanying illustrative drawings of a preferred embodiment'of the invention.

In the drawings: Fig. 1 is a view of a piece of protective sheet material embodying the present invention;

Fig. 2 is a sectional view on the line .22 of Fig. 1;

Fig. 3 is an outer view, in elevation, of a factory window embodying the present invention, one of the panes of glass being broken away to show the protective material;

Fig. 4 is a fragmentary view of the inside of the window, parts of the protective material and elements of the latter being removed for the purpose of illustration; 1 .7

Fig. 5 is a sectional view on the line 5--5 of.

Fig. 4; n

Fig. 6 is an inner view in elevation of the swingable frame of the window illustrated in Fig. 3;,

Fig. 7 is a fragmentary view of the inner surface of the protective material;

Fig. 8 is a fragmentary view of the inner surface of a sheet of glass provided with protectiv material andillustrates a modification; f

the protective ma- Fig. 9 is a sectional View of terial shown in Fig. 8;

Referring now to the drawings more in detail,

the invention is illustrated, as shown inFig. 3,; with reference to a factory window of a Well.

known type which comprises a stationary main frame or sash l0 and a swingable frame I2 mounted therein so that a part of the window can be opened and closed as may be desired.v

In this type of window the glass panels indicated at M are mounted in panel frames having metal frame'members l6 which have substantially co-extensive parts 18 that project inwardly of the window beyond the planes of the glass panels or panes M. The protective material 20 embodying. the present invention is mounted on the inner surface of the window to completely cover all of the glass panes of the latter. It will be under'stood that while a window of one well known type is'illustr'ated, the invention is applicable as well to other types of windows. material 29 and the manner in which the same is associated with the window will now be described in further detail.

As illustrated in Figs. 1 and 2, the protective i material of the present invention comprises a layer of sheet material and more particularly a sheet of padding 22 consisting, as here shown, of-layers 24 and 25 of felted fibrous material disposed at opposite sides of and in fixed rela-.

tion to an intermediate sheet 23 of fabric of a relatively open-weave whereby the adjacent fibres of layers 24 and 25 are inter-connected.

with each other through said fabric '23. Said fibrous'material of layers 24 and 26 may consist of cow hair or of any other suitable fibres.

While the thickness of padding 22 may vary it.

is preferably of the order of about one-half inch. Said padding material is preferably of the type which is placed under floor carpets for cush-' ioning and other purposes, materials of this type being readily available on the market and sold under the trade name Ozite and other trade names.

A layer of wire mesh fabric 30 is secured to the inner surfaces of the sheet of padding .22

Said protective tective material to the window. It will be uni derstood, however, that said grooves 34 may be omitted since the material is pliable-liatndlcanatiw bent around said panel frame members.

The protective sheet material.20 of thepresent! invention is secured to the window preferably adhesively, and for this purpose a layer or coating 36 of any suitable adhesive substance suoh: as, for example, a latex cement or glue,,is-inter,- posed between the inner surfaces of the padding material 22 -ran'dithe glass paneszof the window and can be applied to either or both adjacent; surfaces of thel padding and ofz sa'id' glass panes, respectively, preferably throughoutthe. areas: thereof.

In accordance with the present invention; the protective material which is' appliedto. the swingable frame [2 is separate from the protec:-: tive material which. is secured to J thestationary part Ofl the window; This is illustrated: inal 'ig;

Thus, the swingable frame I2 can be moved to a position for opening and closing the window as may be desired, and since the protective material is in fixed relation to the stationary and movable partsofthe window, respectively, full protection isafiordedwhile at the same itimeipermitting the window to be opened when there is no danger of an air raid and to be immediately closed quickly and at a moment's notice when the danger of an air raid arises.
